Thomas Mann in his novel: The Magic Mountain, approached the very interesting Philosophical topic of the subjective nature of temporal experience.

Much medicine is applied and much anxiety is spent in the avoidance of, or or treatment of "disease"... sometimes to alleviate pain, and always with the hope of increasing life expectancy.

However if indeed there is a subjective element to the construct 'Time' If indeed its subjective or personal experience can be 'sped up' or 'slowed down'; ones experience of ten years might be the same as another's experience of ten days. Rather than the attempt to increase life expectancy, might it not be better to establish the 'mechanisms' to slow ones personal experience of time itself?
